All alcoholic drinks can have a negative effect on your blood pressure, especially if you drink in excess. That’s because alcohol (of any kind) constricts or tightens the muscles that surround your arteries. “When those muscles tighten, it leads to an increase in blood pressure,” says Dr. Desai. Drinking regularly can also contribute to unhealthy weight gain, which can make your blood pressure go up, too, per the Mayo Clinic.
- Nevertheless, there is much evidence that the moderate consumption of alcohol is beneficial for cardiovascular health, beginning from the “French Paradox” – the finding of reduced ischemic heart disease (IHD) among those who regularly drink red wine.
- Human and Animal Rights and Informed Consent This article does not contain any studies with human or animal subjects performed by any of the authors.
- Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict.
- We tested the effect of cross‐over trials through sensitivity analysis by excluding them from the meta‐analysis to check if the effect estimate changed significantly.
- Some evidence suggests that reducing alcohol intake in heavy drinkers could help reduce BP, but much more research is required to validate these observations.
You may need more frequent checks if you have a chronic health condition like heart disease or diabetes. We will combine effect sizes across studies using the fixed‐effect model unless there is substantial statistical heterogeneity between effect sizes. Where there is substantial and unexplained heterogeneity, we will pool data using the random‐effects model. Where trials compare more than one dose of alcohol, each comparison will be handled separately.

A doctor may recommend a person with hypertension not to consume energy drinks. Research from 2019 found that drinking 32 ounces (oz) of energy drink in an hour could increase blood pressure. A 2022 study found that people with severe hypertension who drank 2 or more cups of coffee per day had a higher risk of death from cardiovascular disease. Additionally, doses of over 240 mL were also able to reduce diastolic blood pressure.
Dysfunctional mitochondria are less efficient, can become a source of ROS, and are more likely to initiate apoptosis (Marzetti et al. 2013). The proportion of cardiomyopathy cases attributable to alcohol abuse has ranged from 23 to 40 percent (Piano and Phillips 2014). Recently, Guzzo-Merello and colleagues (2015) reported that, among 282 patients with a dilated cardiomyopathy phenotype, 33 percent had ACM. However, some reports indicate that alcohol-dependent women develop ACM after consuming less alcohol over a shorter period than do age-matched alcohol-dependent men (Fernández-Solà et al. 1997; Urbano-Marquez et al. 1989).
Central nervous system in alcohol-induced hypertension
These complex causal pathways suggest that there are likely heterogeneous therapeutic effects of alcohol reduction on blood pressure. The heterogeneity of interventions for treating alcohol misuse may also contribute to different effects of alcohol reduction on lowering blood pressure. The short-term effects of alcohol (headache, nausea, you know the https://ecosoberhouse.com/ rest) are easy to pinpoint. But there are ways that alcohol affects your body over time that are important to understand. One of the long-term effects of alcohol on your heart is alcoholic cardiomyopathy. This is when your heart-pumping function gets weaker and your heart gets larger due to changes from heavy alcohol use over a long period of time.
- Low‐dose alcohol increased heart rate (HR) within six hours, suggesting that even one glass of wine increases HR.
- For times greater than 13 hours, high doses of alcohol consumption increased blood pressure.
Karatzi 2013Maufrais 2017 and Van De Borne 1997 measured blood pressure before and after treatment but did not report these measurements. We classified seven studies as having high risk of bias (Agewall 2000; Bau 2011; Dumont 2010; Fazio 2004; Karatzi 2013; Maufrais 2017; Van De Borne 1997). Agewall 2000 measured blood pressure upon arrival how alcohol affects blood pressure of participants and did not measure blood pressure after the intervention. The aim of Bau 2011 was to determine the effects of alcohol on heart rate variability, so SBP was not measured in this study. Dumont 2010 measured blood pressure during the study period, but study authors did not provide the before and after measurement of SBP.
Mitochondrial Dysfunction and Changes in Mitochondrial Bioenergetics
Because all of our outcomes of interest provided continuous data, we used the inverse variance approach and a fixed‐effect model to combine effect sizes across studies. Several clinical trials in humans and studies conducted in animal models have reported stimulation of the sympathetic nervous system and increased noradrenaline after consumption of alcohol (Barden 2013; Grassi 1989; Randin 1995; Russ 1991; Zhang 1989). When noradrenaline stimulates the adrenergic receptors located in the heart muscles, heart rate and blood pressure are increased. The molecular mechanisms through which alcohol raises blood pressure are unclear. Previous research suggests that acute alcohol consumption affects the renin–angiotensin–aldosterone system (RAAS) by increasing plasma renin activity (Puddey 1985). The RAAS is responsible for maintaining the balance of fluid and electrolytes.
